Kenwood KRC-656r Hello, I have KRC-656r and rear chanels are not working. Could you please find for me wich power IC is used as a rear channels output amplifier. because the text on the original IC-s is wanished. Thank you.

You would want to bridge 2 of the left channels and 2 of the right channels, essentially combining the power output of the amp.

This article should help you out:http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/how-to-bridge-an-amplifier.html

Essentially you will just be using 2 channels (left, right) instead of 4 (front left, front right, rear left, rear right) essentially combining the power of those outputs. You'll want to check the amp to see if it tells you which of the outputs should be used for the "bridged" method.

The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.

Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.

But, to do the subs justice, you really need at least 300-400 watts to share between them.

The output stage of the amplifier (RH channel) was probabla damaged from the grounded cable. The heat in the speaker means that the coil (d^speaker) is recieveng DC power from the damaged amplifier. Audio amplifiers are not special and can be fixed. In many cases, the output stage is a power MOSFET or a power audio amp IC. The only issue is the availability of the parts in your area.
